polynomials should have big methods?

[nsajko]

For example:

julia> big(Polynomial(rand(3)))
ERROR: MethodError: no method matching big(::Polynomial{Float64, :x})

I would expect big(::Polynomial{Float64, :x}) to return a value of type Polynomial{BigFloat, :x}.

Here I say, we should follow vector as a guide. There we don't have big([1,2,3]) defined. Of course there we have either big.([1,2,3]) or map(big,[1,2,3]). For polynomials, map(big,p) would be the proper way, as the broadcast semantics are different for polynomials than vectors. (Which is maybe a mistake, but one made a long time ago and not really possible to change.)

Didn't occur to me that map would work. map(big, polynomial) indeed works fine, thank you.
